摘　　要：结合大港-枣庄管道工程实际情况,在定向钻穿越施工中运用了光缆与管道同孔回拖技术。实际应用表明,同孔回拖技术在定向钻穿越施工中的应用效果明显,可缩短施工工期,能节省工程投资及规避部分施工风险。同孔回拖技术适用于长距离、地质复杂、征地困难、工期较紧的管道工程。文中阐述了光缆选型及施工方案中拖头制作、相关技术要求及注意事项。According to the actual situation of the Dagang-Zaozhuang Pipeline Project,the technology of optic cable and pipeline dragging back in the same hole of the directional drilling construction was applied. The actual application showed that this technology could shorten the construction period,save the investment and partially avoid the construction risks of the project. This technology is especially favorable for the pipeline projects under the long-distance and complicated geological conditions,as well as in the situations of difficultly expropriating land and the limited construction period. The selection of the optic cable,the preparation of dragging head,the technical demands and some cautions during construction were described in this paper.
